VYILLIAM M. IIOERLE, OF ALLEGHENY, PENNSYLVANIA, ASSIGNOR TO THE PITTSBURG BRASS COMPANY, OF SAME PLACE.

WlCK-RAISING DEVICE F'o'R CENTRAL-DRAFT LAMPS.

SPECIFICATION forming part of Letters Patent No. 451,483, dated May 5, 1891.

Application filed November 28, 1890. Serial No. 5572,8 10. (N0 model.)

provide a device whereby the wick may be raised or lowered on the central-draft tube by a gradual and steady movement, the movement imparted to the wick being spiral in nature and insuring a more even adjustment of the Wick .With relation to the top of the wicktube, where the Wick is ignited.

To these ends myinvention comprises, generally stated, a series of inclined pinions engaging with the wick, said pinions engaging with a gear-wheel adapted to be operated from without the lamp, the inclined pinions upon rotating acting on the principle of the screw to impart an upward spiral movement to the wick traveling on the central-draft tube, all of which will be more fully hereinafter set forth and claimed.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the aocompanying drawings, in which Figure 1 is a vertical section of a central- (lraft lamp embodying my invention. Fig. 2 is a plan view of my improved device, and Fig. 3 is a modified form of gearing for operating the inclined pinions.

Like letters indicate like parts.

The central-draft lamp (1 is of the ordinary form,provided with the central-draft tube 1), encircled by the wick d, the wick-tube, and the other parts essential to the construction of such a lamp; Near the top of the fonnt, within saidfount,issecuredthesupporting-ringe,said supportin g-rin g being held in place by brackets e, soldered or otherwise secured to the interior faces of the fount, or held in any other convenient manner. A gear-wheel f is supported in any suitable manner by the snpporting-ring e, the manner shown being well suited for the purpose, in which the said gear- Wheel is supported by the flange 0 formed on said supporting-ring c. This construction provides for the rotation of the gear-wheel f within the flange 6 In order to impart this rotation to the gear-wheel f, a pinion g, journaled on a shaft h, passing through an opening in the top of the fount, engages with the outer teeth 'f" of the saidgearwheel, and upon the turning of the knob h a rotary movement is imparted to said gear-wheel f. The supporting-ring e is provided with the extension or journal platest', extending in the direction of the Wick (I, said journal-plates t' being arranged at an angle to the wick cl and also slightly canted to one side. Mounted on journals 1, secured to the plates '6, are the pin ions 70. The journal-plates i are arranged to approach within such a distance of the wick d that when the pinions have been journaled thereon said pinions will engage by their teeth It with thebody of the wick with sufficient tenacity to raise the wick upon the rotation of the pinions, as Will more fully appear. The pinions 7c are adjusted at the same angle to the wick as the journal-plates 'i, so that when said pinions are rotated they act, on the principle of the screw, to force the wick up spirally around the central-draft tube. The pinions It further mesh with the interior teeth f of the gear-wheel f. The number of pinions to be employed is to be regulated by the size of the wick.

In Fig. 3 I have illustrated another manner of operating the inclined pinions 70 by which the interior teeth f may be dispensed with. In this case the gear-wheel f is formed with the. depending teeth f, which engage with the pinions 70, as shown, the said pinions being journaled in suitable bearings. The gearwheel f is operated, as before, through the pinion g, engaging with the teeth f of said gear-wheel, the principle involved being the same as that embodied in the above-described construction.

In the operation of my improved wick-raiser when it is desired to raise the wick d the knob h is turned in the proper direction, when the gear-wheel f, through the pinion g, will be rotated. This rotation of the gear-wheel f will in turn impart a like movement to the inclined pinions 7c, meshing with the interior wick maybe readily withdrawn.

teeth of said gear-wheel. The pinions 7.: being arranged at an angle to the wick and slightly canted to one side, with their teeth in engaging with the wick, the rotation of said pinions, acting on the principle of the screw, will impart an upward spiral movement to the wick (Z around the central-draft tube 1). If it is desired to remove the wick entirely, it is only necessary to turn the knob 7t until the teeth of the pinions it have carried the wick beyond the reach of said pinions, when the A new wick may then be adjusted by hand until the lower portion of said wick is engaged by the teeth of the pinions, when upon the rotation of the knob 7L in the opposite direction the said pinions, acting under the same principle, will impart a downward spiral movement to the wick around the central-draft tube until the desired distance is reached.

If the modified form shown in Fig. 3 be employed, the pinion g, meshed with the teeth f of the gear-wheclf, said teeth meshing in turn with the pinions 7., this operation imparts the upward spiral movement to the wick in a manner similar to that shown and described above.

lVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. A wick-raising device having two or more pinions mounted on axes on spiral lines with relation to the central-draft tube engagin g with the wick, an interiorly-toothed wheel engaging said pinion, and mechanism for retating said gear-wheel, substantially as and for the purposes set forth.

A wick-raising device having two or more pinions mounted on spiral lines with relation to the central-draft tube engaging with the wick, an interiorly-toothed wheel engaging said pinions, and a pinion operated from without the fount engaging with the said wheel to rotate said wheel, substantially as and for the purposes set forth.

3. A wick-raising device having two or more inclined pinions engaging with the wick, and a gear-wheel having teeth on its innor face engaging with said pinions, the outer teeth of said gear-wheel engaging with a pinion operated from without the fount, substantially as and for the purposes set forth.

4. The combination, with the supportingring 6, of two or more inclined pinions journaled therein engaging with an interiorlytoothed gear-wheel supported by said su pporting-ring, and a pinion operated from without the fount engaging with said gear-wheel, substantially as and for the purposes setforth.

5. The combination, with the supportingring 6, of the inclined brackets j, the pinions 7;, journaled therein, the gear-wheel f, supported by the flange- 6 the interior teeth f engaging with the pinions 7. and the pinion g, meshing with the teeth of said gear-wheel and operated by the knob h, substantially as and for the purposes set forth.

I testimony whereof I, the said WILLIAM Ill. lloERLE, have hereunto set my hand.
